I am an animal behaviorist primarily interested in behavioral development, play, sexual selection and female mate choice. I am a member and Fellow of the Animal Behavior Society. I maintain a longitudinal study of a population of pronghorn (Antilocapra americana) on the National Bison Range in western Montana. Projects now underway in this study, which has run since 1981, are measurement of costs and benefits of female mate choice and evaluation of the fitness consequences of inbreeding in the population.

My research centers on a closed population of pronghorn (Antilocapra americana) on the National Bison Range in Northwestern Montana. Using an eight generation deep pedigree of the entire population, I am evaluating the hypothesis that female choice for good genes in a mate involves choosing those males with the smallest genetic loads for small effect deleterious mutations.
